University of Iowa undergraduate students have designed and built an augmented-reality sandbox — dubbed Gravbox — that helps users visualize how variations in gravity can affect moving objects. Though ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens in the cosmos. It shapes planets and people, bends light into celestial ...

Neutron stars are laboratories for extreme gravity, dense matter and strong magnetic fields. Modified theories of gravity extend Einstein’s general relativity by introducing new functions of spacetime ...

How can it be that the Moon's mass is a little over 1 percent of Earth's mass, while its gravity is about 17 percent of Earth's gravity? Why aren't the mass and gravity more closely correlated? John ...

Modified gravity theories extend or alter Einstein’s general relativity to address observational puzzles such as the accelerated cosmic expansion, the nature of dark matter and dark energy, and ...

Fundamental probe: Could the International Space Station be the basis for a first test of quantum gravity? (Courtesy: NASA) A global team of researchers is planning to use the International Space ...

WASHINGTON — The European Space Agency’s plan to scale back two big-ticket astrophysics missions is sending NASA back to the drawing board to draft new mission concepts in support of gravity wave and ...

Every fundamental force in nature that acts on astronomical scales must decrease with distance. Otherwise, for example, a distant planet or star would exert a stronger pull on us than Earth does. Life ...
